Yes i maidened my plane yesterday it was a nice sunny day no wind out. Make sure you have the flight control surfaces correct and your CG you say is correct. my elevator was a little high i think the plane is very fast took alot of runway for mine to get up. But once it did get off the ground it was like a bullet. the O.S. .40LA engine screams with an apc 11X6 prop and the plane must fly over 80 mph. and landing was an extreme event.
Without a head wind and the air being dead calm this plane didnt bleed off speed like i thought it might, the use of flaperons would have possably helped it which i'm considering programing into it, before flying it again. But coming in was hot real fast . And there was no tip stalls but i came in real fast and that was scary.
I didnt do any loops or rolls or aerobatic manuvers just pattern flew it. Very responsive plane to the slightest movements of any kind a real Ferrari in the air this is the fastest plane i have ever owned.
So be prepared for that its almost like flying a jet has alot of the same charteristics in my opion. Mine doesnt have the wheel cowlings on it cause i take off from a dirt road and land on the same dirt road. But with the wheel Cowlings on they may tame it down buy giving it some drag under the plane when it's flying.
Whitout The wheel cowlings when its flying you can't even see the landing gear or at least i couldnt.
with a 55 2 stroke the plane will scream just dont go full speed then try to do a roll or loop you may tear the wings off it lol
